When I turn it ON, there is a Beed Sound every 1-2 second and then when it is on the Desktop, beep stops.
As you can see, the screen is not clear and I am afraid this is a hardware issue but thought to double check before give my neighbor the bad news!

BAD NEWS:
The screen went back to that purple or pink colours and the Pixelation is back

The laptop still working though. Still updating the system. But, the screen is bad.

It is either a hardware issue and if so, I am afraid I can't put a smile on my neighbour's face. She was so happy and dazzled when her old machine breathed Linux 2 months ago and was so fast. Now, I guess she will be sad.

Or
It is an overheating issue that is causing this behaviour.

I removed the laptop from my rug that you see on the above picture and kept it on the floor. The Screen back to normal. Few mins and it is bad again.

Re: Graphics/Pixelation - Packard Bell EasyNote Laptop

I have two old RAM (256MB both).
The ones on this picture (below) with orange label/sticker are the RAM on that Laptop. The one with white sticker is mine and the one now on the Laptop where the above picture is testing (256MB RAM) is mine.

I have checked the 4 each on its own. ALL gave me the same screen as you can see on the first picture.

I have never seen that before on my own machines. And, I am wondering why all the RAMs I am using are giving me the same screen? some with 8 errors and some with 81? could it be all the RAMs are bad? or there is something else?

Re: Graphics/Pixelation - Packard Bell EasyNote Laptop

Update:

For two days now, I have been testing the RAMs and it gives me many errors the moment the test starts. When I press "C" for 'Configuration' and choose one of the available options then "7" for restart the test, all the errors disappear.

Was just running a test for both RAMs (total 1GB) which last for +9 hours without any errors and the screen was crystal clear.

Re: Graphics/Pixelation - Packard Bell EasyNote Laptop

1- Firefox Closed
2- Temp dropped down at once
3- Screen became better with few pixelation and these funny colours
4- Refreshed the wallpaper + the two running apps that you can see on the screenshot
5- everything is back to normal

Most likely, it is a software issue that is causing the overheating which is causing the funny screen with weird colours.

I don't think at all it is a hardware failure because if it is, it should not be fine the very moment I close Firefox.

Well, maybe a combination. If the cpu is working hard, there is not enough cooling.

- Are all the fans working?
- Have you removed dust from the inside of the computer?
- Are the incoming and outgoing openings for air clear, so that the air can circulate?
- Maybe you need new cooling paste between the cpu and the cooler.
- Can the computer be moved to a cooler place (no direct sun etc)?
- Maybe you can add a fan.

- Are the incoming and outgoing openings for air clear, so that the air can circulate?

I know that trick so half of the base of the laptop is actually on the air (I am putting it on a small table) and the other half is sitting on the table. So, there should be enough circulation.
In fact, I even removed the cover (when I was testing the RAMs) and the stuff inside were super hot that I couldn't touch for a second. However, the screen was fine. Note that the screen is funny NOT only on Lubuntu BUT also when I turn the machine ON on the POST stage where there is NO OS is loaded still. However, that was before I clean it with my air blower. After I did clean it, it became fine but after a while on the desktop, the issue is back.

I don't know!

- Can the computer be moved to a cooler place (no direct sun etc)?

It is already in a place where the room temp is around 25c-27c max and there is a fan I keep running so there is enough air on the room.

- Maybe you can add a fan.

Add a fan? how to add a fan? you mean use laptop cooler? that thing attached to the base of the laptop? I am not sure this will help.

I have turned the laptop one a while ago. The Temp was below 40C.

You know, Lubuntu is still turns the monitor off after 10 mins so when it went off, I moved the cursor and I noticed the temp has jumped to above 50C and the issue is back.

Computer (Laptop) is totally idle. I am not running anything except System Monitor and XSensors
